Answer:
The length around the figure in terms of r is 2r (
+ 4).
Step-by-step explanation:
The perimeter of an object is the total length of the boundary of the object.
The figure consists two similar semicircle and a rectangle.
Adding the two semicircles, a complete circle is formed. The circumference of a circle = 2r.
The rectangle has a length which is twice its height.
i.e l = 2h
But,
r = 
(the diameters of the semicircles equal the height of the rectangle)
⇒ h = 2r
Thus, one side length of rectangle = 2 × 2r (l = 2 × h)
= 4r
The length around the figure in terms of r is:
= 2r + 4r + 4r
= 2r + 8r
= 2r ( + 4)
The length around the figure in terms of r is 2r ( + 4).
First, you multiply the number by 2, to find how many you had before you ate 1/2 of the candies.
6*2=12
Next, you would divide the number you just got, in this case it would be 12, by 3, because there is 3/4 of the original candy left
12/3=4
This means 1/4 of the original candies was 4, so you add 4 to 12 to find the final answer.
4+12=16
You had 16 candies in the beginning.
Let me know if this doesn't make sense.
